摘要： Techniques are described for specifying and constructing multi-protocol label switching (MPLS) rings. Routers may signal membership within MPLS rings and automatically establish ring-based label switch paths (LSPs) as components of the MPLS rings for packet transport within ring networks. In one example, a router includes a processor configured to establish an MPLS ring having a plurality of ring LSPs. Each of the ring LSPs is configured to transport MPLS packets around the ring network to a different one of the routers operating as an egress router for the respective ring LSP. Moreover, each of the ring LSPs comprises a bidirectional, multipoint-to-point (MP2P) LSP for which any of the routers can operate as an ingress to source packet traffic into the ring LSP for transport to the respective egress router for the ring LSP. Separate protection paths, bypass LSPs, detours or loop-free alternatives need not be signaled.

摘要： Techniques are describe for establishing an overall label switched path (LSP) for load balancing network traffic being sent across a network using the a resource reservation protocol such as Resource Reservation Protocol with Traffic Engineering (RSVP-TE). The techniques include extensions to the RSVP-TE protocol that enable a router to send Path messages for establishing a tunnel that includes a plurality of sub-paths for the overall LSP. The tunnel may comprise a single RSVP-TE Label Switched Path (LSP) that is configured to load balance network traffic across different sub-paths of the RSVP-TE LSP over the network.

摘要： Techniques allow network devices to set up multiple multicast distribution structures for a given multicast group and source. According to the techniques, a multicast protocol is extended to include an instance number in the control messages, where the instance number corresponds to one of a plurality of instances for the multicast group and source. The network device sends a join request for each of the N instances for the multicast group to a plurality of upstream routers. Each of the join requests specifies a different instance of the multicast group to be joined. The source device for the multicast group selects one ofthe N instances, for example using a unicast Equal Cost Multipath (ECMP) hashing algorithm, and sends multicast content for the multicast group to via the multicast distribution structure corresponding to the selected one of the N instances.
